• Optimized for low noise performance in signal chain front ends
• Single configuration suitable for compact surface mount layouts

Applications

• Low Noise Amplifiers (LNAs) for 2 to 8 GHz applications
• Front End Components for Wi-Fi, Bluetooth, and ZigBee systems
• ISM Band Applications and Mesh Networks

Procurement Notes

Verify component authenticity through authorized CEL distributors or certified suppliers. Confirm that the part matches the specified M04 package dimensions and electrical characteristics provided in the official datasheet. Ensure compliance with relevant RoHS directives before integration into final assemblies.

Selection Notes

Select this component when designing circuits requiring a silicon NPN transistor with a 15 GHz transition frequency and low noise figure around 1.7 dB. The M04 package offers a compact footprint suitable for space-constrained PCB designs operating within the 2 to 6 GHz range.

Part Context

This component belongs to the CEL Silicon Bipolar Transistors product line, specifically categorized under Single Transistors. It serves as a discrete solution for RF signal processing, complementing other CEL offerings such as GaAs FETs and MMIC amplifiers in wireless connectivity and optical markets.

Replacement Considerations

The NE677M04-A is electrically equivalent to the NEC 2SC5751. Designers may consider the 2SC5751 as a direct substitute if sourcing from NEC/CEL channels, ensuring pinout compatibility with the M04/SOT-343F package.
